Multiplier and MPC in Economics

These flashcards summarize key concepts related to Marginal Propensity to Consume and the multiplier in economics.

MPC

Marginal Propensity to Consume, a measure of the proportion of additional income that is spent on consumption.

Multiplier Effect

The idea that an initial increase in spending will lead to a larger increase in overall economic output.

Multiplier Formula

The multiplier is calculated as $1 / (1 - MPC)$, where MPC is the marginal propensity to consume.

Value of Multiplier with MPC 0.5

If MPC is 0.5, the multiplier value is 2, calculated as $1 / (1 - 0.5)$.

Value of Multiplier with MPC 0.1

If MPC is 0.1, the multiplier value is 10, calculated as $1 / (1 - 0.1)$.

Impact of MPC on Multiplier

The higher the MPC, the larger the multiplier effect, meaning more income is used for consumption.
